This patch series removes a fair amount of cruft from sys/types.h and
bits/types.h, obsoletes four additional typedefs that should not
be used in public interfaces anymore (caddr_t, daddr_t, loff_t,
register_t), and restricts sys/types.h’s definition of u_intN_t and
register_t to __USE_MISC (i.e. they are no longer present in strict
conformance modes).

It depends on the “Use a proper C tokenizer to implement the obsolete
typedefs test” patch, which has just been resubmitted separately.
Unlike that patch, this series is not intended to be appropriate for
backport to release branches.

Zack Weinberg (8):
  Move inttypes.h and stdint.h to stdlib.
  Define register_t using bits/typesizes.h macros.
  sys/types.h: Don’t define u_intN_t or register_t unless __USE_MISC.
  Add caddr_t, daddr_t, and loff_t to the set of obsolete typedefs.
  Simplify definition of __time64_t.
  Clean up bits/types.h.
  Create bits/types headers for most remaining __T_defined macros.
  Don’t conditionalize declarations of ldiv_t, lldiv_t, __gwchar_t.
